Coronal Mass Ejection
Catalog: M2M_CATALOG
Start Time: 2026-06-22T04:08Z ( STEREO A: SECCHI/COR2 )
All Detecting Spacecrafts:
STEREO A: SECCHI/COR2
SOHO: LASCO/C2
SOHO: LASCO/C3
GOES: CCOR-1
Activity ID: 2026-06-22T04:08:00-CME-001 (version 1)
Note Keyword:
Faint: Faint event; may affect type assignment
OVR: Event partially overlaps with another CME
Source Signature Keyword:
FIL: Filament eruption
Morphology Keyword:
Note: This CME is visible to the SW in STEREO A COR2 imagery and faintly to the SW in SOHO LASCO C2/C3 and GOES CCOR-1 imagery. The source of this CME appears to be filament ejecta from farsided eruption activity possibly associated with old Active Regions 14464 and 14467. This CME overlaps the CME first seen to the SW in STEREO A COR2 imagery at 2026-06-22T03:23Z.
